Introducing Affordances through the carpeting of public spaces: Affordances as a tool for stimulating curiosity and exploration within our built environment
Public spaces are the places where people come together in the physical environment. They are precious as they have in them the possibility of bringing together people with different cultures and backgrounds. In some cases, however these important spots within our cities are not designed to maximize their capacity for human exploration. As seen in the city of Skopje (North Macedonia) large public spaces fail to attract users as they do not offer enough furnishing or objects of exploration. Design through Affordance can provide many of these underused spaces with additional layer of furnishing that aims to trigger the explorative nature within human beings. The concept appeals to the creation of spaces that are not defined in terms of functions, but rather in terms of possibilities for use. This enables public spaces to go beyond the concepts of aesthetics, style or identity and relate directly to human nature and the direct interaction between us and our physical environment.Architecture, Urbanism and Building Science
Effectiveness of propensity score methods with density estimation in identifying overlap for causal inference
For causal inference, sufficient overlap is needed. It is possible to use propensity scores with the positivity assumption to ensure overlap is present. However, positivity is not enough to properly identify the region of overlap. For this, propensity scores need to be used in combination with density estimation. This project aims to evaluate this method, discovering in which scenarios it performs well or fails in identifying the region of overlap. More specifically, how it scales with more features or outliers, and how using different classifiers affects the performance. The method was tested with samples from a simulated dataset. The predicted overlap was compared with the true overlap of the known distributions.Following the experiments, the method seems to perform best when the treatment and control groups share one region of overlap. In this case, logistic regression works best out of the classifiers that were tested. The overall performance drops when the two groups have multiple regions of overlap. For this, the random forest classifier performs best instead. Throughout all scenarios, the performance of the model drops with increasing dimensionality. Furthermore, having a small percentage of outliers only slightly affects the model. With more outliers, logistic regression is the only classifier further affected.CSE3000 Research ProjectComputer Science and Engineerin
Conducive Business Environment to Regain Competitiveness for Sustainable Firm Growth in Special Economic Zone of Batam, Indonesia
The declining competitiveness of Batam has significant impact on Batam firms’ growth. Lack of supporting infrastructure, and lack of good public governance i.e., the dualism power of local government (PemKot) Batam and local authority (BP) Batam has caused the declining competitiveness and declining firms’ growth in Batam. Good supporting infrastructure, good public governance, productive manpower and good research and development institutions in Batam as part of conducive business environment is critical for regaining competitiveness that impacts firms’ growth in Batam. It is urgent to transform Batam from the status of Free Trade Zone (FTZ) to Special Economic Zone (SEZ) in the near future which has proven to be a powerful engine for regional economy growths and excellence, and to be able to compete in a highly competitive business environment of ASEAN Economic Community (AEC) that has been realized recently.

ARTIFICIAL NEURAL NETWORK AND STOCK PRICE PREDICTION
The main objective of this research is to examine the performance of neural network (NN) to predict stock price. This research propose to use daily closing price of TELKOM share for the observation period. Authors propose to use TELKOM share because it is one of the most liquid and blue chip stock in Indonesian Stock Exchange (IDX). This research use purposive sampling. The authors propose to use Artificial Intelligence Neural Network (ANN) to predict stock price. From literature review ANN can predict stock price more accurately than traditional way like linear regression. The Artificial Neural Network (ANN) model use backpropagation algorithm for training session and feed forward NN for testing the output. The authors propose ANN with five nodes outperform ANN with fewer (two) nodes. The reason is that the information contained in five nodes ANN provide more accurate information than two node ANN. Consequently ANN with five nodes can predict stock price better and more accurately than ANN with two nodes. The average percentage error should be less for ANN with five nodes then the percentage error of ANN with two node

Keep Your Eyes On The Prize: An assessment framework for the regulatory arrangement on the use of medical technology in hospitals
Medical technology is evolving at a remarkable rate, prompted by its major role in health care services. The Health Care Inspectorate monitors this technological advance and should take action whenever the quality of care and/or patient safety is at risk. Regulation is therefore inevitable. However, as far as the use of medical technology in care institutions is concerned, there are still some gaps. This research explores how a regulatory arrangement specifically aimed at the use of medical technology in hospitals could complement the Inspectorate?s current regulatory arrangement and how it should take form. The 2006 Twenteborg accident, claiming the life of a patient, served as the motive for this research, as it is a typical example of the complexity entailed in regulating the use of medical technology in hospitals. The main research question was therefore: ‘What amendments can be made in the Health Care Inspectorate’s regulatory arrangement to enhance patient safety when using medical technology in hospitals?’ In order to find the answer, the research included an analysis of the current regulatory arrangement of the Inspectorate, an analysis of several theories on regulation, a field analysis, and an analysis on the specific complexities entailed in regulating the use of medical technology. The research also included a design & evaluation phase, to make an assessment framework for a regulatory arrangement specifically aimed at the use of medical technology in hospitals and assess the Inspectorate?s current regulatory arrangement. The Inspectorate?s current regulatory arrangement includes a cycle of enforcement and three inspection instruments, namely phased, thematic and incident-based supervision. Medical technology is regulated by means of the Medical Devices Act and the Care Institutions Quality Act. The first act regulates the production and trade of medical devices and is thus essentially meant for manufacturers, whereas the latter regulates the use of medical technology, thus essentially regulating care institutions. In this way a clear distinction is made between supervision on the production and trade of medical devices and supervision on the use of these medical devices. However, actual practice has shown that it is hardly feasible to keep these two apart. The cycle of enforcement and the inspection instruments are based on three regulation theories namely system-based, risk-based and responsive regulation. Fundamental to the system-based regulatory approach is that the regulatee should have a self-regulatory capacity and thus aims for regulation on the system-level. The risk-based approach aims for selective regulation and requires the regulator to \u84pick important problems and fix them?. The responsive regulation approach focuses on interventionist response and tries to establish a synergy between punishment and persuasion. Each theory has a number of opportunities and risks that need to be considered when applying them. Many of the risks or complexities that were identified in the theory were confirmed by the field analysis. The field analysis also provided some additional insights into other (practical) complexities. An analysis of the complexities has revealed that they are mostly created by the multi-actor environment, by organizational and technical issues, or by the formal obligations the Inspectorate has to comply with. An adequate regulatory arrangement and thus the standards of the assessment framework should be designed in such a way that the opportunities and the risks identified in the analyses of the theories and the field analysis should be reckoned with, in that one should try to gain advantages from the opportunities and try to reduce or prevent the risks. Furthermore, as the Inspectorate?s current regulatory arrangement consists of a combination of different regulatory theories, the assessment framework should also provide standards which enable a practicable combination of theories. Keeping the above in mind, I have designed an assessment framework. It is intended to serve as an assessment tool for the Inspectorate and can be interpreted as a normative checklist or guideline to verify if and the extent to which the standards are imbedded in the regulatory arrangement. Upon assessing the Inspectorate?s current regulatory arrangement by means of the assessment framework, a number of shortcomings were identified including communication issues, accountability issues and issues regarding the content and focus of the actual inspections. The recommendations to the Inspectorate therefore also include suggestions as to how to improve on these aspects. The general conclusion of this research is that the Inspectorate?s current regulatory arrangement still has a number of gaps, especially with regard to the use of medical technology in hospitals. These gaps can be narrowed by a more meticulous design of the regulatory arrangement. The general complexity of regulating the use of medical technology is mainly due to the multiplicity of aspects, each of which should be given careful consideration. The title of this report was inspired in the light of this complexity. Keep Your Eyes on the Prize is a warning that one should not lose sight of the main objective, which is the quality of care, with the focus on patient safety. The main recommendation is therefore to use the designed assessment framework as a guideline to gain perspective on regulating the use of medical technology in hospitals. It should be noted, however, that the designed assessment framework still needs some finishing touches, as it was not feasible to include them in the limited time frame of this research. The finishing touches include the aspects of a measurable assessment, which should enable the user to obtain a valuable rating of the situation, and the terms of reference, which should specify the usage. As medical technology is now also increasingly used in nursing homes, it may be worthwhile finding out if the assessment framework can also be applied in a wider setting than just hospitals.Policy, Organization, Law & Gaming; Policy AnalysisSafety Science GroupTechnology, Policy and Managemen
